Cancer contraction

特許 権利維持 PROBLEM TO BE SOLVED: To provide a collection method of data for cancer contraction verification usable for simple extracorporeal diagnosis of cancer contraction, and to execute the method simply with high sensitivity. ; SOLUTION: In this method for collecting data used for verification of cancer contraction includes a process for adding hematoporphyrin and/or its derivative to lymphocyte collected from a subject, a process for irradiating a mixture acquired in the process with light having a specific wavelength and generating excitation emission from the hematoporphyrin and/or its derivative, and a process for measuring the emission quantity generated in the process.
